  1. 1. Thermal Modelling of Permanent Magnet Synchronous Motor Windings in Heavy-Duty Electric Vehicles

    University essay from Linköpings universitet/Fordonssystem

    Author : Ken Dahl; [2023]
    Keywords : PMSM; permanent magnet synchronous motor; synchronous motor; black-box modelling; black-box models; thermal modelling; lumped parameter thermal network; LPTN; electric machine; EM; EV; electric vehicle; winding;

    Abstract : A significant challenge with permanent magnet synchronous motors (PMSMs) is thermal management. Thermal stress can lead to irreversible damage to components, and to enable efficient cooling, a thermal model is needed. READ MORE

  5. 5. Fatigue Life Analysis of Weld Ends : Using FE-Calculations and Mechanical Testing

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Victor Ljungdahl; [2018]
    Keywords : Comparison; Effective notch method; Testing; Weld End; Jämförelse; Effective notch metoden; Provning; Svetslut;

    Abstract : Fatigue life estimation of welds is a complex issue since the characteristics of each weld are unique depending on load case, geometry and properties. Fatigue life estimation on weld ends is limited and often the weakest point of a weld. READ MORE
